# Gemini CLI

Use Gemini in one-shot mode with a positional prompt (avoid interactive mode).

Quick start

- `gemini "Answer this question..."`
- `gemini --model <name> "Prompt..."`
- `gemini --output-format json "Return JSON"`

Extensions

- List: `gemini --list-extensions`
- Manage: `gemini extensions <command>`

Notes

- If auth is required, run `gemini` once interactively and follow the login flow.
- Avoid `--yolo` for safety.
